Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hurdle in which a storage space is narrow and the height of the hurdle can be easily set during use.
[0002]
[Prior art]
A hurdle that is widely used at present is provided with a column portion extending in the vertical direction on a pedestal portion that is placed on the ground, and the column portion is supported by this column portion. When using such a conventional hurdle, the height from the ground to the crosspiece (the height of the hurdle) is set by adjusting the length of the support column.
[0003]
And when storing the conventional hurdle, in order to save storage space, it has stored in the warehouse etc. in the state where the support | pillar part was shortened most.
[0004]
[Problems to be solved by the invention]
However, when storing such a conventional hurdle, even in the state where the column portion is the shortest, a right triangle portion having a straight line connecting the crosspiece and the end of the pedestal portion becomes a dead space. There was a problem that.
[0005]
An object of the present invention is to provide a hurdle capable of making the storage space narrower than conventional and capable of setting the height of the hurdle very easily during use.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention described in claim 1 includes a substantially “U” -shaped outer frame in which one end of each column is fixed to both ends of the crosspiece, and the crosspiece of the outer frame. The inner frame of a substantially “U” shape, which has a crosspiece having a shorter dimension than that of the crosspiece, and one end of the support is fixed to both ends of the crosspiece, and two support members. A joint that can be rotated and locked is interposed between the outer side of one end of each of the column members and the inner side of each of the end portions of the outer frame, and the other ends of the two column members. Between the inner side of the inner frame and the outer sides of the end portions of the inner frame, a joint portion that can be rotated and locked is interposed, and the four joint portions are arranged with the inner frame placed on the ground. When the horizontal frame portion of the outer frame is rotated upward and the ground height of the horizontal frame portion of the outer frame is displayed, And it is characterized in that provided on the rotational position of the joint to respond.
[0007]
In order to achieve the above object, the invention according to claim 2 is characterized in that the outer frame has a substantially “U” -shaped outer frame in which one end of the support column is fixed to both ends of the crosspiece. The above-mentioned 2 is composed of a substantially “U” -shaped inner frame having a crosspiece having a shorter dimension than the crosspiece and having one end of the post fixed to both ends of the crosspiece, and two support members. A joint that can be rotated and locked is interposed between the outer side of one end of each of the two column members and the inner side of each end of the outer frame, and each of the two column members Between the inner side of the other end and the outer side of the end portion of the inner frame, a joint portion that can be rotated and locked is interposed, and the four joints in a state where the outer frame is placed on the ground. When the horizontal section of the inner frame is moved upward by rotating the section, the display indicating the ground height of the horizontal section of the inner frame is And it is characterized in that provided on the rotational position of the joint portion and the corresponding high.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is a perspective view showing the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a substantially “U” -shaped outer frame configured by fixing one end of each of the support columns 12 and 13 to both ends of the crosspiece 11 using connection pipes 14 and 15.
[0010]
2 is a substantially “U” -shaped configuration in which one end of each of the support columns 22 and 23 is fixed to both ends of a crosspiece 21 having a shorter dimension than the crosspiece 11 of the outer frame 1 using connection pipes 24 and 25. It is an inner frame.
[0011]
Reference numerals 3 and 4 are support members, and joint portions 5 and 6 are interposed between the outer side of one end of the support members 3 and 4 and the inner side of the end of the outer frame 1, and the inner side of the other end and the inner frame 2. Joint portions 7 and 8 are interposed between the outer sides of the two ends.
[0012]
Here, the structure of the joint portion will be described by taking the joint portion 7 as an example. 2A is an enlarged view of the joint portion 7, and FIG. 2B is a cross-sectional view thereof.
[0013]
As shown in FIG. 2B, the joint portion 7 includes two connection pipes 71 and 72 and one inscribed pipe 73. The inscribed pipe 73 is fixed to one of the connecting pipes 71, 71, and the other connecting pipe is rotatable in a state of being in contact with the inscribed pipe 73. Since a frictional force is generated between the inner wall of the connecting pipe in a rotatable state and the outer peripheral wall of the inscribed pipe 73, the connecting pipe does not rotate unless an external force is applied.
[0014]
Further, as shown in FIG. 2A, an indication 74 indicating a reference position is provided on the surface of one of the two connection pipes 72, and a rotation is provided on the surface of the other connection pipe 71. A display 75 indicating the ground height (the height of the hurdle) of the crosspiece 11 of the outer frame 1 corresponding to the moving position is provided.
[0015]
In the present embodiment, a display indicating the reference position and a display indicating the ground height of the crosspiece 11 are made on all of the four joint portions 5, 6, 7 and 8 shown in FIG.
[0016]
Next, the operation of the present embodiment configured as described above will be described.
[0017]
First, since the present embodiment can be made flat as shown in FIG. 1 in the storage state, the storage space can be remarkably saved as compared with the conventional hurdle.
[0018]
Next, when this embodiment is used, first, as shown in FIG. 3, the joint portions 5 and 5 are arranged so that the column portions 12 and 13 of the outer frame 1 are in the vertical direction with the inner frame 2 placed on the ground. 6 is rotated. At this time, the user can set the column parts 12 and 13 of the outer frame 1 in the vertical direction and at the same time the height of the hurdle by simply matching the display of the reference position of the joint parts 5 and 6 with “Acm”. Can be set to Acm.
[0019]
Here, when increasing the height of the hurdle, a desired height is selected, and the joint portions 5 to 8 are set so that the display of the height of the four joint portions 5 to 8 matches the display of the reference position. What is necessary is just to rotate (refer FIG. 4, FIG. 5).
[0020]
In this way, the user can set the height of the hurdle very easily just by rotating the joint so that the display of the desired height provided on the joint matches the display of the reference position. .
[0021]
In the present embodiment, the height of the hurdle is configured to be selected from Acm, Bcm, and Ccm. However, the height is not limited to three and may be any number. Furthermore, this display 75 does not need to be performed using numbers, and may be performed using colors. For example, the height of the hurdle may correspond to the display color, such as 106 cm for black and 83 cm for red.
[0022]
In the embodiment described above, the height of the crosspiece 11 of the outer frame 1 when the inner frame 2 is placed on the ground is configured to be displayed on the joints 5 to 8. You may comprise so that the height of the crosspiece part 21 of the inner frame 2 when the frame 1 is mounted on the ground is displayed on the joint parts 5-8.
[0023]
【The invention's effect】
As described above, according to the present invention, the storage space can be reduced as compared with the conventional case, and the height of the hurdle can be set very easily during use.
